SEPARATING-MACHIN.

To cLZZ whom it may concern.-

Be it known that I, ANDREW J. MILLER, of Arion, in the county of Scioto and State of Ohio, have inventcdcertain new and useful .Improvements in SeparatingMachines; and

I` do hereby declare the following to be a full, clear, and exact description of the invention,

`such as will enable others skilled in the art inafter.

The object of my invention is to provide a hulling-machinein which a belt is used which is provided with crosspieccs, and to which a constant shaking motion is given,so as to separate the hulls from the beans or peas.

Figure 1 is a side elevation of a machine, partly in section, embodying my invention. Fig. 2 is a plan view of the same, the hopper being removed.

A represents a suitable frame-work of any suitable description; B, the hopper; C, the hulling-cylinder, and D the concave, which is provided with teeth in the usual manner. Beans or peas are poured into the hopper,and are fed into the revolving cylinder with one hand While the operating-crank E is being turned with the other. The teeth are arranged spirally upon the cylinder for the purpose of moving the hulls and loosened beans or peas from one end of the concave to the other before they are discharged upon the endless belt F. This belt passes over rollers G at opposite ends of the machine, and is provided With a number of cross-slats, H, upon its inner side,and against which the polygonal wheel I strikes for the purpose of imparting to this endless belt a shaking movement. The apron is placed at a suitable inclination and presents a smooth surface upon its outer side; but, having the slats II secured to its inner side, each time the wheel I strikes one of the slats it causes the belt to shake in such a manner as to cause the peas or beans to separate from the hulls and run down the inclined belt into any receptacle placed to receive them. This polygonal Wheel Iis placed upon a shaft, J, which extends across the framework just over the top of the endless belt, and which wheel is caused to revolve by frictional cont-act with the belt, as the belt is caused to move by the operating shaft or roller. The edges of the wheel, striking against the cross-pieces of the belt, impart a vertical reciprocating motion to the belt, so as to constantly shake the beans and peas which may have remained in the hulls,or which may have been caught among the loose hulls, so that they will roll down the belt. The vertical movement of the belt carries the hulls up over the upper end of the machine and discharges them from that point.

In order to prevent any of the hulls adhering to the belt, the spring-actuated cleaningboard L is used. This board is provided with journals at its lower corners, and is forced upward at its upper edge against the, under side of the endless belt by means of a suitable spring, N. The upper edge of the board, by

keeping in contact with the belt, brushes oft any adhering substances and prevents them from being dropped among the hulled peas or beans.

As here shown, the hulling-cylinder is operated by the belt O, which passes over the large Wheel l? upon the operating-shaft around the pulley Q, which is placed upon the cylinder-shaft; but I do not limit myself to any particular form of construction so far as gearing the operating parts together is concerned.

Either the concave may be provided with a series of perforations, through which the beans and peas may be discharged directly upon the endless belt, or they are to be discharged With the hulls through the opening at one en d of the concave, as may be preferred. As here shown, the concave is provided With perforationsfor the escape of the hulled beans or peas, so that they may be discharged from the belts independently of the hulls.

Having thus described my invention, I claim In :t separating-machine, the combination of communicated to the Whole Wdtli of the belt, the pulleys G, the inclined belt F, mounted substantially as shown and described.
